What is chardet?

The chardet npm package is a character encoding detector library, which allows you to determine the encoding of a given piece of text or a file. It is based on the character detection component of the ICU (International Components for Unicode) project and can be useful when dealing with text data that does not have encoding information.

What are chardet's main functionalities?

Detecting encoding of a text buffer

This code reads a file and uses chardet to detect the encoding of its content. The 'detect' function takes a buffer and returns the name of the encoding it believes the text is in.

const chardet = require('chardet');
const fs = require('fs');

fs.readFile('/path/to/file', (err, data) => {
  if (err) throw err;
  const encoding = chardet.detect(data);
  console.log(encoding);
});

Detecting encoding with confidence

This code creates a buffer from a string and uses chardet's 'detectAll' function to get an array of possible encodings along with their confidence scores.

const chardet = require('chardet');

const buffer = Buffer.from('Some text with unknown encoding');
const result = chardet.detectAll(buffer);
console.log(result);

Detecting encoding of a file stream

This code creates a read stream from a file and uses chardet's 'detectStream' function to detect the encoding of the streamed content asynchronously.

const chardet = require('chardet');
const fs = require('fs');

const stream = fs.createReadStream('/path/to/file');
chardet.detectStream(stream).then(encoding => {
  console.log(encoding);
});
